When someone has cancer they typically lose a lot of weight. Is this due to an inability to eat due to nausea or is there something about fighting cancer that is metabolically expensive?

How are the Covid19 vaccines progressing at the moment? Posted: 08 Sep 2020 07:19 AM PDT Have any/many failed and been dropped already? If so, was that due to side effects of lack of efficacy? How many are looking promising still? And what are the best estimates as to global public roll out? submitted by /u/Curiosityitis [link] [comments]

Why do Catalan numbers show up in this square root expression? Posted: 08 Sep 2020 03:14 AM PDT A = R - sqrt(R2 - 1) Where R = 5 * 10n (with a relatively big n) e.g. when n=16, we find: A=1.00000000000000000000000000000000010000000000000000000000000000000002000000000000000000000000000000000500000000000000000000000000000000140000000000000000000000000000000042000000000000000000000000000000013200000000000000000000000000000004290000000000000000000000000000001430000000000000000000000000000000486200000000000000000000000000000167960000000000000000000000000000058786000e-17 submitted by /u/BanX [link] [comments]

(Biochemistry) Why does a sucrose solution turn red during a Benedict's Test? Posted: 07 Sep 2020 09:42 PM PDT Okay, so I am looking for an explanation for why am getting a particular result between Benedict's Test and Sucrose. According to many websites, sucrose is not a reducing sugar. However, I've done Benedict's Test multiple times in the past and the results are that a sucrose solution turns brick red. So the Theory goes: Sucrose is a non-reducing sugar as its sucrose "aldehyde" group is participating in glycosidic linkage and the fructose "ketone" group is also participating in the linkage. So why am I getting Red? EDIT: Furthermore, the sucrose solution has not been heated in dilute acid as far as I know. ​ submitted by /u/Hikaritoyamino [link] [comments]

How close can an object orbit something? Posted: 07 Sep 2020 10:19 AM PDT Assuming the planet is a perfect sphere with no atmosphere. It would have to be orbiting faster and faster as you got closer to the surface right? So for say an earth sized object at what point would an object have to be travelling faster than light to maintain its orbit? An inch? A milimeter? submitted by /u/ILurkTilIDont [link] [comments]

Hiroshima and Nagasaki nuclear bomb: why is it that leukemia was the most common type of cancer in the first years, but then after even decades other forms of solid cancer like breast cancer or colon cancer where more common? Posted: 06 Sep 2020 09:03 PM PDT I have been researching about the lasting effects of radiation and I am intrigued to know why is it that leukemia was the most common form of cancer just 2-5 years after the event, but then breast cancer appears soooo long afterwards. Aren't cells nuclei damaged since the moment of the event? What determines the latancy period in different types of cancer? Or is that dependent on the amount radiation? submitted by /u/Germartel93 [link] [comments]
